Matrix math7/10/2023 ![]() For (n x m) matrices where n*m =0) for kSizeMax ROOT provides the following matrix classes, among others:įor a dense matrix, elements are arranged in memory in a ROW-wise fashion. ![]() ![]() The decompositions are used in matrix inversion, equation solving. In addition eigen-Vector analysis and several matrix decomposition have been added (LU,QRH,Cholesky,Bunch-Kaufman and SVD). The present package implements all the basic algorithms dealing with vectors, matrices, matrix columns, rows, diagonals, etc. The ROOT linear algebra package provides a complete environment in ROOT to perform matrix calculations such as matrix-vector and matrix-matrix multiplications and other linear algebra calculations like equation solving and eigenvalue decompositions.
